Application filed. ctober 6, 1921. Serial No. 565,744.

To all whom t may con-061m:

Be it known that I, Eimer. F. Simona, a citizen of the United States of America, residing at Detroit. in the county of lVayne and State of Michigan, have invented' certain new and usefullmprovements in Condenscrs, of which the following is a specification, reference being had therein to the accompanying` drawings.

This invention relates to a condensing apl paratus and has special reference to an apparatus that may be advantageously used as part of a refrigeratory system for condensing ammonia gasor vapor.

The object of this invention is to provide a compact condenser for a refrigeratory apparatus by which ammonia gas or vapor may be expeditiously condensed, the condenser including a main tank containing a cooling agent, an outer coil in the tank, an inner coil in the outer coil and communicating with the tank, and a receiver in the tank communicating with the outer coil. rlhis arrangement provides primary and secondary cooling zones with the latter Zone serving functionally as a sealing agent about connections forming part of the primary cooling zone.

rlheY above and other objects are attained by a construction that will be hereinafter described and then claimed, and reference will now be had to the drawing, wherein Figure 1` is a longitudinal sectional view of the condensing apparatus7 partly in elevation, and

Fig. 2 is an end view of a portion of the apparatus.

In the drawings, the reference numeral 1 denotes a main tank or receptacle having end walls 2 and 3 and before these walls are placed in position the greater part of the apparatus is assembled within the tank or receptacle, and the interior thereof constitutes a secondary cooling zone adapted to receive a cooling agent, as water, from a pipe 4l connected to the tank at one end thereof.

Suitably mounted within the main tank 1, in spaced relation to the walls thereof, is an outer coil of tubing 5 which has one end convolution thereof connected to a coupling vmember 6 and the other end convolution connected to a coupling member 7. The coupling member 7 has a conventional form of stuifing box 8 and extending through said stuiiing box is the open end 9 of an inner coil of tubtubing lin spaced relation to said inner coil of tubing beingouter coilA of the tubing, so as to provide a passage 11 between-the coils of tubing 5 and 10. rlrhe opposite end of the inner 'coil 'of tubing 10 extends through a stuiiing bor; 12 of thefcoupling member 5 and then through the end wall 2 of the main tank. llith the inner coil of tubing 10 open adjacent the coupling member 7 and communicating with the main tank, it is obvious that the water within the tank can flow through the inner coil of tubing 10 and provide what l term a primary cooling device, with the passage 11 between the coils of tubing servingas a primary cooling zone.

Extending through the end wall 2 of the main tank and connected to the couplingY member 6 is a gas or vapor inlet pipe 13 and said coupling member has a chamber 14 which permits of the gas* and vapor from the pipe 13 entering the primary cooling zone or passage 11 between the coils of tubing 5 and 10.

The coupling member Y has a chamber 15 to receive the Igas or vapor from the passage 11 and connected to the coupling membeuT is a pipe 16 leading to a receiver or secondary cooling device 17 which is placed concentric of the coil of tubing 5, in spaced relation thereto and preferably against the end wall 3 of the main tank 1. The receiver 17 has a suitable outlet pipe 18 extendingfrom a point -adjacent the inner end of the receiver through the outer end thereof and through the end wall 2 of the main tank 1.

With the circulation of water or otherr cooling agent maintained through the main tank 1 it is obvious thatthe outerA coil of tubing 5 and the receiver 17 are cooled by ing 10, disposed throughout the the water and by circulating the water through the inner coil of tubing 10, the gas or vapor in the passage 11 and the receiver 17 will be cooled and condensed.

I attach considerable importance to the compact manner in which the greater part of the apparatus is arranged within the tank, and since this tank may be water and air tight there is very little danger of am- Y monia or other injurious gases escaping.

With the receiver containing the liquefied vapor, the liquid may be maintained in a cool state for a low condensing pressure.r For instance with the cooling agent kof the secondary zone at approximately sixty-eight degrees, Fahrenheit, a condensingr pressure as low as one hundred and fifteen is obtainable, and probably lower, which is a desideratnm with all condensing systems.

One embodiment of my invention has been illustrated, but it is to be understood that the structural elements are susceptible to such changes, in size, shape and manner ot assemblage as fall within the scope of the appended claims.

What I claim is l. A condensing apparatus comprising a main tank adapted to receive acooling' agent, a receiver in said main tank, an outer coil about said receiver and communicating4 therewith, and an inner coil in said outer coil and communicating with said main tank. 2. A condensingV apparatus as in claim l. and coupling' members supporting' said outer coil and through which the ends oit said inner coil extend.

3. In a condensing apparatus wherein coils of tubing, one within the'other, afford a cooling zone for vapors by circulating a cooling 'agent in the innermost coil of tubing; means for condensing such vapors as escape liquecation in the Cooling zone, com prising a receiver to receive vapor, and means for utilizing the coolingI agent for cooling the receiver in advance of utilizing' it in the aforementioned cooling zone.

In testimony whereof I atiix my signature in presence of two witnesses.
